Great bass requires large drivers that can move a lot of air.

But it’s nothing compared to what arealsubwoofer or a larger bass-focused driver setup can do.

Here’s Brane X’s custom subwoofer.

The Brane X speaker has arealsubwoofer, alongside two tweeters and two mid-range woofers.

First, here’s how Brane’s subwoofer is different to a regular sub.

Fundamentally, it’s all about the magnet design, and overcoming air pressure.

Here’s Brane X’s custom subwoofer.

The problem with a subwoofer in a small, sealed space like a Bluetooth speaker is air pressure.

Far more than is reasonable to drive from a battery.

Hence, no subwoofers in portable speakers.

I liken it to one of these exoskeletons that are designed to help people lift heavy objects.

The Brane team agrees that’s a fair analogy, although they think of it like a Steadicam.

(To be fair, the first versiondidn’twork, but they fixed that.)

The clear version of the Brane X on the right isn’t for sale, but it shows off the forward-firing tweeters and angled woofers (the sub is on the bottom).

To be clear, though, it’s not too much.

It absolutely adds hugely to the experience.

I also heard it in comparison to the similarly sized JBL Xtreme 3, and the considerably largerUE Hyperboom.

Switching between the JBL and the Brane X was like going from 2D to 3D.

sounded so thin in comparison.

However, these two speakers do have a huge advantage over the Brane X: price.

The Brane X is also a beast.

Even with them, I suspect that putting it on the same shelf as your fine china is unwise.

A release in the rest of the world is targeted for late in 2024.
